bacon, hams, fish, and other comestible substances may be smoked anddried in a more simple and expeditious manner and with less shrinkagethan heretofore and to that system of smoking and drying wherein thesmoke is generated in a separate chamber and then passed through thechamber wherein the substances to be treated are placed. According toour invention we provide for extracting the moisture from the smokeafter it has passed over the substances and mixing it with fresh smokeand, if desired, rewarming it in order to render it fit for againpassing into contact with the substances. In practice the floor of thechamber wherein the substances to be treated are placed is perforated,and the smoke which is delivered through this perforated floor by a fanor blower is drawn from the top of the smoke-generating chamber, so asnot to unnecessarily disturb the burnt ashes and draw them into the fanwith the smoke. The two chambers are connected at the upper end, so thatthe smoke after passing over the substances will return to thesmoke-generating chamber, flowing in its course through a condenserormoisture-extractor, wherein the moisture carried by the air isdeposited, and thence, if necessary, through an air-warmer.

In practice two or more chambers for containing substances to be treatedare generally 2 2, Fig. 1; and Fig. 3 is a transverse section on theline 3 3, Fig. 1.

a is the chamber wherein the smoke is generated and which is hereinafterfor convenience of description referred to as the generating-chamber,and b b are chambers wherein the substances to be treated are placed,and which for convenience of description we will hereinafter refer to asthe smoking-chambers.

The floor c of the generating-chamber a, upon which the sawdust or othersmoke-producing material is to smolder, is surrounded by a perforatedpipe (I for admitting air for supporting combustion, the supply of airthrough the said perforated pipes being regulated by any suitable means.In some cases the generating-chamber a is provided with one or moreshelves 6 in order to afford additional space upon which thesmoke-producing substances can be placed, and in this case the saidshelf or shelves is or are provided with perforated pipes d, as beforedescribed. This construction is shown in Fig. l.

e is a rotary fan or blower which will vary in size according to theamount of force required and which is designed to exhaust the smoke fromthe generating-chambera through the pipesf and to deliver itinto thesmokingchambers 12 I) through the pipe g, which pipe is below eachsmoking-chamber b 5 provided with a series of arms or branches h h fordistributing the smoke as evenly as possible over the floor i, which ismade of wire-gauze or other suitable perforated material. These branchpipes are provided with valves or dampers h h,by which the smoke can beshut off from either smoking-chamber b orb and admitted to theothersmoking-chamber, (or chambers, if two or more are employed.) Asshown, the branch pipes h h are also provided with downwardly-extendingnozzles to render the distribution of the smoke more even than would bethe case if the said branch pipes delivered horizontally or in an upwarddirection. j is a pipe through which the smoke passes from thesmoking-chambers b I) back to the generating-chamber a. This pipe, asshown, is provided in each smoking-chamber with lar cowl q, controlledby a valve 1".

two apertures k 70, which can be closed by covers Z l, and with anotheraperture 077., which can be closed by a cover a, the said aperture mbeing arranged immediately in conjunction with a ventilator or cowl 0,which can be controlled by a valve 10. The generating-chamber Ct is alsoprovided with a simi- With this arrangement all the smoke-laden airwithin the generating-chamber a and smoking-chambers b 1) maybe eithercontinuously circulated, being drawn from the generatingchamber athrough the pipesfand delivered to the smoking-chambers b I) through thepipe 9 and branch arms h, whence it returns to the generating-chain hera through the pipe j, or by more or less opening the valves p p and rthe fan 9 will draw some fresh air through the cowl q, and acorresponding amount of smoke-laden air will be discharged from thechambersb 5' through the cowls 0 0, the lids 'n n being pushed back toallow of this. The lids Z Z can also serve for more or less adjustingthe speed at which the current of smoke-laden air flows through theapparatus. If the smoke is to be excluded from oneo thesmoking-chambers, the valves h h in connection with this'chamber areclosed to prevent the admission of smoke from the fan, and the lids'l Zand n are also placed over their respective openings to exclude smokereturning to the generating-chamber through the pipe j.

In order to provide for introducing fresh air by the fan and blowing outthe smoke from either smoking-chamber, we provide, in connection withthe pipes f fof the fan,valves f f, which serve for shutting offcommunication between the generating-chamber and the interior of the fanand opening communication between the latter and the atmosphere throughopenings f f in the pipes ff, Figs. 1 and 2. The fan and parts of thepipes ff outside the generating-chamber are preferably lagged or coveredwith non-conducting material to prevent the loss of heat.

' s is the moisture-extractor, which may be of any suitable constructionand which is arranged upon the pipej in such a manner that as thesmoke-laden air renters the generating-chamber a it passes through thesaid extractor. Thisextractorismaderemovable, so that it may be readilydetached when not required for use.

if is a heating-coil which is used in some cases, if necessary, in orderto reheat the smoke-laden air before it is again forced into thesmoking-chambers b b. This coil 21 can be heated from a stove it,arranged outside. the apparatus, as shown in Figs. 2 and 3,

r, Fig. 2, indicates a trap or passage for afiording access to theinterior of the gener-' ating-chamber at for. introducing thesmokegenerating fuel into the said chamber, and w is the door of thesaid passage. In practice we prefer to employ two doors for preventingthrough communication between the external atmosphere and the interiorof the generating-chamber a, one door being arranged to be closed whilethe other door is opened, and vice versa. This additional door isindicated at w. 7

ac is the door for affording access to the smoking-chamber b.

It is to be understood that the doors to and 00 are so arranged thatthey can be hermetically closed during the operation of the apparatus.Suitable windows are arranged either in the doors or in the walls of theseveral chambers for permitting of inspecting the progress of thesmoking process without opening the doors.

3 y are bars upon which the articles to be treated, such as sides ofbacon, are hung during the smoking operation, and z is a chain or thelike connected to a lever in connection with each of the valves p and rfor opening or closing the latter, as required.

A thermometer such as .2, Figs. 2 and 3, is advantageously applied tothe apparatus in such a manner that the internal temperature can beascertained without opening the apparatus.

Among the advantages of the construction hereinbefore described we maymention the following: first, a great economy of space, as thearrangement permits of the materials to be treated nearer the floorinstead of seven or eight feet from the floor, as has generallyheretofore been usual, thereby permitting of say two tiers of substancebeing treated in a house which heretofore was adapted for treating onetier only, and, second, the shrinkage of the substances under treatmentis considerably less than heretofore because of there being no directcontact with the hot ashes of the sawdust, and, furthermore, the thetemperature being under control the saving of time in effecting theprocess of smoking is considerable.

Having now particularly described and ascertained the nature of our saidinvention and in what manner the same is to be performed, we declarethat what we claim is 1.
